1. The gills of this insect nymph are located inside a special chamber (rectum) within its abdomen. The nymph breathes by drawing water in and out of its hind end.
A.
B.
2. This decapod is omnivorous, feeding upon vegetation or preying upon snails and other macroinvertebrates and small fish. It has two defense mechanisms. It has large claws on its first pair of legs for pinching. Also, it has expendable legs. When this creature is attacked, muscles in the walking legs may contract at creases and may break off. The missing legs regenerate with molt.
3. This aquatic insect has long oar-like hind legs used for swimming and feeds by inserting its beak into its prey and sucking out its bodily fluids.
4. This insect undergoes an incomplete metamorphosis. This benthic macroinvertebrate is fairly sensitive to changes in the ecological integrity of a body of water and serves as one of the indicator organisms observed by participants in the Illinois RiverWatch monitoring project.
5. This invertebrate must remain moist. To prevent desiccation, the organism produces a protective coat of mucus which also aids in travel as it moves by rhythmic waves of muscular contractions, leaving a slime trail behind.
6. This fish gives birth to live offspring instead of laying eggs and is generally seen in small creeks or along vegetation in ponds and lakes.
7. This aquatic larva will change into an adult form that prefers a moist subterranean habitat in an upper humus-rich soil horizon (beneath rotting logs, within leaf litter, or under grassy detritus), except during breeding season when it returns to water.
8. This grouping of organisms, found within a shallow pond in a forested area, has a firm gelatinous texture and filters food from water by use of lophophores crowned with tiny tentacles.
9. This snake is diurnal during spring and fall but becomes nocturnal in summer and hibernates during winter’s cold. The nonvenomous snake is sometimes called “water moccasin” perhaps due to its aquatic habits, foraging for fish and amphibians, basking along shorelines, loafing on branches overhanging water, and taking shelter under debris at water’s edge.
10. This frog’s voice is often heard in early spring during its breeding season. Its loud voice belies its small size of only 4 cm or 1 ½ inches snout-to-vent length at maturity.
